2 Claims.

This invention relates to antirattling devices for use on windows and doors to prevent the same from rattling.

More particularly the invention relates to a device of this type embodying certain improvements and has for its principal object the provision of a device that may be easily inserted between the frame and the window sash without requiring removal of the window in order to attach the device thereto, and further, the provision of a device of this type that is exceptionally simple, inexpensive and effective as cushioning means and which will eliminate any binding that would hamper the free movement of the window in its frame.

According to the teachings of the invention, an antirattling device is provided that is formed of sheet metal sumciently resilient and of a construction admitting of easy application, say, at

0 the lower or upper face of the window sash, whereby a right angle shoulder may be provided on the device that will bear tightly against the corner of the window and the resulting leg extending laterally from the device fixedly anchored 25. to this upper or lower face of the window sash and the extending portion of the device inserted between the meeting sides or surfaces of the frame and window sash provided with an arcuate formation that will furnish sufficient tension to hold the window sash against rattling in its frame without resulting in any binding hindering the free movement of the window.

Specifically, the invention contemplates the provision of an antirattling device adapted to be fixedly anchored either to the upper or lower-face of a window sash or like member and extend between the meeting sides of the window sash and the frame. The device preferably comprises an arcuate portion and a pair of leg members, one

of the leg members being bent angularly with respect to the other leg member, the arcuate portion being so shaped that a greater part thereof will overlie said angularly bent leg member whereby, when this arcuate portion is inserted between the window sash and frame, both leg members will embrace the corner of the window sash in surface engagement therewith.

Other objects and advantages of the invention will be apparent from the following detail .descriptions taken in connection with the accompanying drawing which forms a part hereof.

In the drawing:

Figure 1 is a perspective view of a portion of a Window sash and its frame illustrating an antirattling device embodying the invention, and its manner of application;

Fig. 2 is a detail view partly in section and partly in elevation illustrating this antirattling device in side elevation inserted between the meet- 5 ing sides of the window sash and its frame;

Figs. 3 and 4 illustrate several forms of this antirattling device with the arcuate formationvarying in each instance; I

Fig.5 is a similar view illustrating an anti- 10 rattling device havingan arcuate portion that will cause an undesirable binding between the window and the frame;

Fig. 6 is a view similar to Fig. 2 but having the antirattling device shown in Fig. 5 inserted be- 15 tween the meeting sides of the window sash and its frame member, but before being fixedly anchored to the window sash.

Fig. 7 illustrates the bulging shoulder formed as the lower leg is fixedly anchored to the window 20 sash, this bulge resulting from an arcuate formation that causes an undesirable binding as the window sash is moved in its frame, this view together with Figs. 5 and 6, being included herein to show by comparison the advantages of an arcuate portion that is formed properly.

The antirattling device 2 herein disclosed is preferably made of a strip of thin metal that will, have resilient qualities when formed with an arcuate portion 3. The body of the device represented at 4 is provided with a leg 5 formed angular'ly with respect to the body. However, in efiect, body 4 also constitutes a leg similar to leg 5, both being of flat formation adapted to fit tightly against the corner of a sash as shown in Fig. 2, the inner faces of these legs having surface engagement with the window sash. The angularity between legs 4 and 5 will depend upon the angularity between side 6 and face 1 of the sash mem- 40 her 8. Face 1 may be either the upper face or the lower face. It is quite customary to find it sloping slightly, and consequently, not exactly at right angles to side 6. In this event, legs l and 5 may be likewise angularly formed so that when 45 the device is mounted, as shown in Figs. 1 and 2, the faces thereof will be in surface engagement with side 6 and face 1.

Leg 5 may be perforated or punched to receive a nail 9 serving as a fastening means for fixedly anchoring the device to window sash 8 in the fashion shown in Fig. 1. As an aid to prevent any turning or twisting of the antirattling device 2 about nail 9, the two outer corners of leg 5 are 55 formed in the shape of prongs Ill adapted to penetrate sash member 8.

The arcuate formation of portion 3 extends approximately to point II, this portion then continuing in a slightly bent and straightly formed tip l2. Lines AB in Figs. 3 and 4 illustrate portion 3 having a substantial part of its arcuate formation extending away from the plane of body 4 in the direction of leg 5 and substantially overlying this leg 5. A small part of this arcuate formation may lie on the opposite side of line A-B. The purpose of this formation as I am able to observe is to force the inner faces of legs 4 and 5 to engage flatly against side 6 and face 1 of sash member 8, and hold corner 14 at the juncture of legs 4 and 5 in embracing relation with the corner l5 of sash member 8. It seems that if an excessive portion of the arcuate formation of part 3 does not lie to the left of line A-B, a pressure is created holding legs 4 and 5 away from the corner of sash member 8, which will result in corner I 4 bulging away from corner l5.

Figs. 6 and '7 illustrate the formation which corner [4 is forced to assume when an undesirable portion of the arcuate formation of part 3 lies to the left of line AB. Fig. 5 illustrates a device having an excessive portion of the arcuate formation extending beyond line A--B. When this device is inserted between sash member 8 and frame I6, arcuate portion 3 will tend to force and hold leg 5 away from face I. Also, leg 4 will be forced away from side 6 and corner M will be held away from corner l5 of sash member 8 and side 6 instead of embracing or hugging corner [5 of sash member 8. When this condition exists, anchoring leg 5 to face I by securing means 9 causes the bulge or hump at corner M to increase and exert a pressure against the side of frame member 16 that will hinder the free movement of sash member 8 in the frame. I have actually found by experience that bulge M will exert a pressure that will actually prevent the window from being raised unless an unusual effort is made to raise the window.

It is, therefore, important that arcuate portion 3 be formed properly, as shown for example in Figs. 3 and 4, and not cause a pressure to be exerted when it is inserted between the meeting sides of the sash member and frame that will result in a binding action hampering a reasonable free movement of the sash member in the frame. Any suitable type of metal may be used but I have found that very desirable results are obtained if the device is made of soft and pliable material that will readily yield but still keep its resiliency sufficient to effect a proper cushioning action between the sash member and the frame without causing any undesirable binding.

Antirattling device 2 may be easily inserted by any person at the underside of the window sash so that the arcuate portion 3 will be slipped between the meeting sides of the sash member and the frame as illustrated in Fig. 1. It will be disposed in the concealed position so as not to affect the appearance of the parts. Moreover, arcuate member 3 and tip I2 are so formed that they will not mar or scratch sash member 8 and frame l6. As explained above, this construction results in corner [4 hugging corner [5 of sash member 8. Consequently, the resiliency exerted by arcuate member 3, when it is compressed, results in sufficient pressure to keep sash member 8 tightly held in the frame to prevent rattling without causing any part of the device to bind unduly and hamper movement of sash member 8. The antirattling device is simple, inexpensive and very easily applied.

Without further elaboration, the foregoing will so fully explain the gist of my invention that others may, by applying current knowledge, readily adopt the same for use under varying conditions of service, without eliminating certain features, which may properly be said to constitute the essential items of novelty involved, which items are intended to be defined and secured to me by the following claims.

I claim:

1. An antirattling device comprising a resilient body portion having an angularly bent base leg at one end and an arcuate portion at the other end, said arcuate portion including a curved part, the greater part of which overlies said angularly bent base leg, each of said ends being adapted to engage angularly disposed surfaces, the curved part exerting a reactive pressure at the juncture of said ends to cause the same to seek a relatively tight engagement with the same surface against which the arcuate portion abuts when said base leg is tight in place.

2. An antirattling device comprising a resilient body portion having an angularly bent base leg at one end and an arcuate portion at the other end, said arcuate portion including a curved part, the greater part of which overlies said angularly bent base leg, each of said ends adapted to engage angularly disposed surfaces, and means associated with one of said ends to so secure said device that said curved part exerts a reactive pressure at the juncture of said ends to cause the same to seek a relatively tight engagement with the same surface against which the arcuate portion abuts when said base leg is tight in place.
